I recently read an article that lists 12 common half-truths many of us have accepted as facts. Here are a few: peanuts aren’t really nuts (they’re legumes), a palm tree isn’t a tree (it’s a plant), a koala bear isn’t really a bear (it’s a marsupial), and a penny is actually worth more than one cent—costing about two cents to make. Whether they are of consequence or not, we find ourselves swimming in half-truths.
